I have attempted to do something a bit different from the more traditional game walkthrough here. While most walkthroughs are content to simply present the solutions to the puzzles and steps necessary to complete the game, I have tried for a somewhat more detailed approach. Where possible, I give the reasoning behind puzzle solutions so that you will know the "why" as well as the "how". I also comment on the storyline (something most walkthroughs ignore) and direct you to parts of the game that I think are of interest even if they are not necessary for the solution.
In short, think of these less as walkthroughs and more of guided tours to the game worlds. So, grab your camera and water bottle, put on some comfortable walking shoes and follow along with one of our tour guides below.
